Stainless Steel Cookware and Utensil Manufacturing: Optimizing Deep Drawing with Bed Cushions
The Metallurgical Challenge of Drawing Stainless Steel
Stainless steel grades like AISI 304 and 201 work-harden rapidly during drawing. Unlike mild steel, which stretches easily, stainless steel requires precise blank-holding pressure to pull metal smoothly into deep utensil shapes without tearing the cup bottom or wrinkling the rim.
Cookware Stamping Machinery Workflow
| Production Stage | Recommended Press | Key Tooling Feature |
|---|---|---|
| Circle Blanking | Milap MMC-80 Ton High-Speed C-Frame | High-clearance sheer dies cutting clean, burr-free round disks |
| First Deep Draw | Milap MH-150 Ton Hydraulic Press with Die Cushion | Controlled descent with regulated blank-holding pressure |
| Edge Trimming & Beading | Milap MMC-30 Ton Inclinable Press | Rotary trimming tools curling clean edges on pots and basins |
| Handle Piercing & Embossing | Milap MMC-20 Ton Ungeared Press | Quick-stroke progressive piercing of handle rivet holes |
Eliminating Orange Peel and Thinning Defects
Milap Hydraulic Deep Drawing Presses (MH Series) feature adjustable draw speed controls. Decelerating ram velocity right as metal flows past the die shoulder prevents microscopic material necking ("orange peel") and maintains uniform wall thickness.
